"Certain power supply series from Huntkey (like V-Power and Green Star) are labeled with their peak wattage instead of their continuous wattage. So far in our reviews only Titan 650 W (sold in the US as the first version of Best Buy's Rocketfish 700 W) and Jumper 550 didn't explode during our tests. We've already reviewed the 450 W version from Balance King series, which also exploded in a very unusual way. Let's see if the 500 W model will survive our tests."
